8.1 Application Information

The TPD1E10B09 is a single-channel back-to-back diode that protects one bidirectional signal line from electrostatic discharge and surge pulses. Because the diode is bidirectional, TPD1E10B09 protects signals that have positive or negative polarity. During normal operation, the diode behaves as a 10-pF capacitance to ground. Board layout is critical for optimal performance of any diode.

Placement: The diode should be placed very close to the external connector for optimal performance. It is best to place the diode on the line that it is protecting.

Layout: Pin 1 of the diode should be right over the protected signal line. There should a thick and short trace from pin 2 to ground. For an example, see the Layout section.
